The most important thing for a team leader to encourage in the storming stage of group development is open, constructive communication that surfaces and works through conflict rather than suppressing it.

Storming stage in brief

In Tuckman’s model, the storming stage is when team members begin to express real opinions, leading to disagreement, power struggles, and tension. Performance often dips here because energy goes into conflict and competition instead of productive work.

What the leader must encourage

During storming, the leader’s key task is to create a climate where people can safely:

  • Voice disagreements and concerns openly rather than engaging in hidden conflict.
  • Listen to one another and seek understanding, not just “win” arguments.
  • Clarify goals, roles, and expectations together so the team can move toward shared norms.

In many textbooks and exams, this is often summarized as encouraging open communication and constructive conflict resolution during the storming stage.

Why this is “most important”

If conflict is avoided or shut down, the team tends to get stuck in storming, with ongoing power struggles and low cohesion. When the leader instead encourages honest dialogue and helps the team resolve issues, the group can progress into the norming stage, where cooperation and unity increase.

TL;DR:
For the question “which of the following is most important for the team leader to encourage during the storming stage of group development?” the best choice is the option that describes open communication and constructive expression/resolution of conflict among team members.
